Windows 10 上的 PIP 和路径问题

Question

So common error with several possible causes. Running

 pip install requests

results in the following error

Fatal error in launcher: Unable to create process using '"c:\\users\\foo\\appdata\\local\\programs\\python\\python36\\python.exe" "C:\\Users\\foo\\AppData\\Local\\Programs\\Python\\Python36\\Scripts\\pip.exe"

I've just installed Python 3.77 on Windows 10 to this location (after removing previous versions)

c:\\python37\\

After searching here Fatal error in launcher: Unable to create process using ""C:\\Program Files (x86)\\Python33\\python.exe" "C:\\Program Files (x86)\\Python33\\pip.exe""

Pip - Fatal error in launcher: Unable to create process using '"'

I tried using

python -m pip install --upgrade pip 

which results in

Requirement already up-to-date: pip in c:\\python37\\lib\\site-packages (20.0.2)

And thinking it is a pathing issue I tried the following command but no difference

setx PATH "%PATH%;C:\\python37\\lib\\site-packages"

What should I try next?

Answer 1

to make it easier.. uninstall python 3.7 and reinstall.. when installing do custom and all users.. it will prompt for should add Python to Path..

You can also try future installations with Package Managers like Chocolatey. Its like apt-get / YUM / Brew for windows. chocolatey.org/install
